        <h1>Example of displaying a web image (JPEG, PNG) using Cornerstone</h1>
        <p class="lead">
            Enter a URL for a JPEG or PNG image below to view it using cornerstone
        </p>
        <p>
            This example illustrates how to use the cornerstoneWebImageLoader to get a standard web
            image (JPEG, PNG)  and display it using cornerstone.
        </p>
        <strong>If you get an HTTP error and your URL is correct, it is probably because the server is not configured to
            allow <a href="http://en.wikipedia.org/wiki/Cross-origin_resource_sharing">Cross Origin Requests</a>.
            Most browsers will allow you to enable cross domain requests via settings or command line switches,
            you can start chrome with the command line switch <code>--disable-web-security</code> to allow cross origin requests.
            See the <a href="http://enable-cors.org/">Enable CORS site</a> for information about CORS.
